Traffic Rules and Signals in Japan

To ensure a safe journey with a car rental in Japan, it is important to know the Japanese traffic rules.
In order to avoid any unexpected problems, here is a detail explanation of important information you should know when driving in Japan.

The driver's seat is on the right

In most overseas countries, the driver's seat can typically be found on the left side of the car, however in Japan, it can be found on the right.
If you are accustomed to driving on the left, please be aware of the difference in driving experience.

Japan drives on the left

On Japanese roads, cars drive on the left side. If you are someone used to driving on the opposite side, please be cautious when driving. Be careful not to drive the wrong way, especially when entering an intersection or roundabout.

Mandatory seat belts

In Japan, the wearing of seat belts is mandatory for all rear seat passengers as well as the driver and front passenger. Failure to wear seat belts will result in penalties for the driver. It is especially easy to forget to fasten belts when seated in the back seat, so please ensure everyone is securely fastened before leaving.

Mandatory car seats for children

In Japan, the use of a car seat is required by law for children under the age of six. When reserving a rental car, be sure to request the appropriate seat if you are traveling with a child under 6 years old.

The types and meanings of Japanese traffic signals

Much like the rest of the world, traffic signals are composed of the three colors, green, yellow, and red in Japan. However, there are some minor differences between Japan and other countries, so please be sure to check before driving.

Green Light

You are allowed to proceed.

Yellow Light

You must not proceed unless you cannot fully stop in a safe manner.

Red Light

You must not proceed.
*Please note that while it common to be able to turn right at a red light if it is safe to do so in some countries, it is illegal in Japan. Please be sure to stop at red lights.
However, if there is a traffic light immediately after the right turn and the light is red, there is no need to stop.

Red Light and Arrows

Regardless of the color of the light, you may only proceed in the direction of the arrow displayed. Please do not proceed in any other direction.
In addition, when a right turn arrow is displayed, turning (U-turn) is allowed only if there is no signing prohibiting U-turns.

Flashing yellow lights

You may proceed with caution, paying attention to other traffic. Please slow down or stop where necessary.

Flashing red lights

You must come to a complete stop at the designated stop line.
Once you have checked that it is safe to continue, you may proceed with caution, paying attention to other traffic.
